The rapid Urbanization and Industrialization all over the world has resulted in large
deposition of Plastic waste. This waste can be utilized under proper condition to reduce the
Cement content in Concrete.M20 concrete is used for most of the constructional works, since it
gives maximum strength. The strength of this concrete was compared with concrete obtained
of shredded Plastic waste varying from 2-8%. Experimental investigations comprised of testing
physical requirements of coarse aggregates, fine aggregates, cement and the modifier. M20
concrete was prepared as per IS SP: 23-1982. The said percentage of modifier was blended
with the cement concrete mix and the optimum modifier content was found. Cubes were cast
and tested for 1, 3, 7, 14 and 28 day strength. These tests revealed that by adding modifier, the
strength of concrete increased. At 5% optimum modifier content, the strength of the modified
concrete was found to be 1.2 times greater than the plain cement concrete. By using Plastic
waste as modifier, we can reduce the quantity of cement and sand by their weight, hence
decreasing the overall cost of construction .The Modified cement concrete can be used in the
construction of small drainage works and rigid pavement. Which leads to decrease in the overall
thickness of the pavement.
